CUT PILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 391,652, dated October23I 1888,

Application filed February ll. 1888. Serial No. 263,741.

To aZZ whom it may concern:

Be it known that I, TOM I. SHUTTLEWORTH, a citizen of the United States,and a resident of Amsterdam', Montgomery county, New York, have inventedcertain Improvements in Gut'Pile Fabrics, of which the following is aspecification.

My invention consists of a certain improvement in that class of pilefabrics which are woven double and subsequently cut apart, the object ofmy invention being to facilitate the weaving of such double fabric, andto produce a fabric having a firm back and close pile with the use ineach fabric of a less number of figuring warp-th reads than are employedin making the usual single fabric. This obj ect I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which- Figure lis an exaggerated diagram illustrating a section of myimproved fabric, the section being taken on a line transversely to thewarp. Figs. 2 and 3 are longitudinal sections, respectively, on thelines l 2 and 3 4, Fig. l; and Fig. 4 is a view illustrating a slightlymodified form of thefabric.

In the-present method of producing figured cut pile fabrics by weavingthe fabric double, carrying the figuring warp-thread across from onebacking to the other, and then severing these figuring warp threadsmidway between the two backings, it is the usual custom to dis-` tributethe figuring warp-threads in each fabric uniformly from one side of thefabric to the other-that is to say, there will bein both the upper andlower sheds a certain proportion of figuring warp-threads for each dentof the reed, and where stuffing-warps are used the dents are undulycrowded and free shedding of the warps is interfered with. I desire toovercome this objection, and yet adhere to the plan of weaving thefabric double and then cutting it apart, so as to produce a fabric having a firm body and a sufficiently close pile with considerably lessthan the amount of nguring-warp now used in making a cut pile fabric bythe usual plan of weaving the fabric with loops and then cutting thelatter. I therefore alternate the disposal of the sets of figur- (Nospecimens.)

ing warp-threads in the two sheds. Thus, for example, the upper shed mayhave sets of figuring warp-threads disposed in the dents l 35 7, Src.,of the reed, there being no figuring warp-threads in the dents 2 4 6 8,the., While in the lower shed the disposal of the sets of figuringwarp-threads is reversed, said sets occupying the dents 2 4 6 S, &c;, ofthe reed, while there are no figuring Warpthreads in the dents l 3 57,85e., the vacant dents of the reed in each shed bei ng occupied by thestuffingwarps, which therefore do not in any way interfere with the freeshedding of the guriug-warps in the other dents of the reed. Theconsequence of this is, that viewing the fabric transversely,

as in Fig. l, the pilev is formed alternately by a thread drawn downfrom the upper backing and looped into the lower backing, and by athread drawn up from the lower backing and looped into the upperbacking, and when the fabric is severed the pile will be formed bylongitudinal rows of tufts projecting upward from the bac-king, thetufts ofevery other row consisting of the projecting ends of figuringwarp-threads extending from end to end of the fabric and buried in thebacking, while the tufts of the alternate rows consist of the projectingends of independent loops simply tied into the backing bythefilling-threads, the stufting-warps being disposed alongside of theserows of independent loops, so as to provide for the proper stiffcning ofthe fabric.

In the drawings, the letters a represent the figuring warp-threads, bthe binding-warps, d the stufing-warps, and f the binding-wefts, threeof these being used in the present instance for each transverse row ofpile-loops, although more or less than three binders may be used, ifdesired.I

In carrying out my invention it is not absolutely necessary that thetufts derived from the threads buried in the backing and the tuftsformed by the independent loops should be in single rows, as a series ofrows of tufts formed by independent loops may alternate with a series ofrows of tufts derived from the buried warps. (See Fig. 4, forinstance.)I/Vhere two stufiing-warps are used for each row of tufts formed by theindependent loops, one of said warps may be on each side of the row oftufts, ternate rows Consisting of tufts formed'by sinas shown at d inFig. v4I. gle independent loops tied into the backing Having thusdescribed my invention, what and disposed by the side of one o1'morestnfng- I claim, and desire to secure by Letters Pat- Warps, allsubstantially as specified. i5 5 ent, is In testimony whereof I havesigned my naine A out pile fabric in which binding warps to thisspecification in the presence of two suband wefts and stufng-warpsforming a, bncksoribing witnesses.
